Definitions

  • the present invention relates to a massage device, comprising a main body having a gripping section, adapted to be held by a user; a massaging head, and an actuator, configured to effect a reciprocating movement of the massaging head relative to the gripping section.
  • Percussive massage may comprise rapid, percussive tapping, slapping and cupping of an area of the human body.
  • a massage device for providing relief from sore muscles and other tissues by applying pressure to the body with the reciprocating motion of a massage head is known from US 10,314,762 B1 .
  • US 5,902,293 discloses a can body connected to a sucking pump to withdraw air from inside the can body, which is fitted with a vibrator to enhance the curative effects of traditional Chinese can sucking therapy.
  • An apparatus to administer a skin care composition including a housing, a suction tip to engage the skin, a suction pump connected to a motor, a vibrator, and a power supply is known from US 2016/0074641 A1 .
  • the present invention has the object of providing a user-friendly massage device and a method of operation of a massaging device.
  • the invention provides a massage device, comprising a main body having a gripping section, adapted to be held by a user; a massaging head, and an actuator, configured to effect a reciprocating movement of the massaging head relative to the gripping section, wherein the massaging head comprises a negative pressure cavity connected to a suction pump.
  • Percussive massage therapy which is applied by the reciprocating movement of the massaging head provides strong, rapid, short-duration strokes. This action relieves muscle tension and increases blood flow to the affected area and aids in relieving pain in soft tissues. Cupping therapy, generating local negative pressure on the skin increases blood circulation to the area, where the cups are placed. This is known to relieve muscle tension, improve overall blood flow and promote cell repair.
  • negative pressure can be applied simultaneously together with powerful strokes of a massaging head, which aids to combine cupping and percussive massage therapy in one device. This improves the efficiency of sports-related muscle recovery and pain therapy.
  • the negative pressure cavity is open towards a front end of the massaging head, to apply a negative pressure on a massage recipient during the massage operation.
  • the negative pressure cavity may be connected via a tube to a suction pump, wherein the suction pump is arranged on the main body. Due to the independent arrangement of the suction pump from the massage head, the massage head may be designed rather compact and robust.
  • the suction pump could have an electrical drive or may be driven by the actuator effecting the reciprocating movement of the massaging head.
  • the suction pump could be an electric diaphragm air pump.
  • the suction pump is arranged in the gripping section.
  • the massage device could be provided with a pneumatic valve, which enables to adjust the level of negative pressure.
  • the pneumatic valve may be part of the suction pump or may be provided in between the suction pump and massage head. This could be done by measuring the negative pressure level i.e. with an air pressure sensor and adjusting the negative pressure to a desired level by controlling the opening of the pneumatic valve through a feedback loop. This allows the users to set the negative pressure level individually, for example depending on the type and intensity of the sport activity or depending on the body, which will receive the massage.
  • the massaging head comprises an insert and a base body, wherein the insert is removably arranged in the base body.
  • the insert is removably arranged in the base body.
  • the shape of the insert protruding from the base body may be generally ball-shaped, flat, fork-shaped, or cone-shaped. Purely percussive massaging inserts without negative pressure cavity could be used, if the user prefers desires to apply only percussive massage.
  • cupping massage inserts with a negative pressure cavity may be provided.
  • the cupping massage inserts may be U-shaped in their cross-section or have a cone-shaped opening.
  • the cupping massage inserts may be used for a cupping massage application, when activating the suction pump only. When activating the suction pump and the actuator, a combined cupping and percussive massage application is provided.
  • the insert or the negative pressure cavity receiving the insert in the base body may be provided with a connector, which facilitates replacements of other inserts and retains them in the base body during the massage.
  • inserts can be made of variety of materials, such as i.e. polymer, metal, glass, composite, and may possess different hardness values.
  • the insert is at least partially arranged in the negative pressure cavity.
  • the negative pressure cavity may be partially void despite the inserted insert. This may reduce the size, weight and production cost of the inserts, and provide an extra volume for the negative pressure, lowering pressure amplitudes. Further, the insert may protrude over the negative pressure cavity in the direction of reciprocating movement.
  • the insert forms a part of the negative pressure cavity.
  • the insert defines the form of the negative pressure cavity, by providing the outer walls of the negative pressure cavity.
  • a sealing is provided in between the insert and the base body of the massage head. This may improve the fastening of the inserts in the base body of the massaging head, in particular by increasing friction forces in between the insert and the base body. Also, the sealing may reduce or avoids air leakage.
  • the insert may be held by a connector, such as a mechanical coupling, in the base body of the massage head.
  • the negative pressure in the negative pressure cavity is adapted to hold the insert in the base body. This may eliminate the necessity of the usage of a connector for fastening the inserts in the base body of the massaging head.
  • the actuator is arranged at least partially in the gripping section. This saves space and allows providing a compact massaging device, which is easy to handle by the users.
  • the actuator is arranged above the gripping section.
  • the actuator comprises a crank drive, having a drive shaft, which is eccentrically fixed in a crank body, wherein the crank body provides a bearing for a piston rod.
  • the diameter of the bearing is bigger than twice the radius of the eccentricity of the fixation of the drive shaft in the crank body. Based on lever rule, a small eccentricity allows gaining more percussive force from drive shaft of the motor; consequently a more efficient use of motor power.
  • the relatively large bearing compared to the eccentricity may have a high mechanical durability.
  • the inventive bearing design may reduce friction, and, thus, the device may be operated at higher speed and/or with a stronger massaging force.
  • At least a rear end of the massaging head is formed as a piston guided in a bushing, wherein the actuator is connected via a pin in a hollow section in the rear end of the piston.
  • the massaging device comprises an acceleration sensor or pressure sensor or both, configured to detect the acceleration of or pressure applied by the massaging head.
  • the massaging device may further comprise a display, indicating the pressure applied by the massaging head derived from the pressure sensor or the acceleration sensor. Accordingly, the user can control and adjust the desired pressure level.
  • the display may be adapted to display the beneficial orientation of the massaging device, derived from the measured acceleration. Thus, the user may be guided to optimize the position of the device in a way to make the best use of the massage.
  • the massage head may have a weight of 20 g to 100 g, preferably 40 g to 60 g.
  • the invention further provides a massaging insert forming a part of a negative pressure cavity.
  • the negative pressure cavity is open towards the front of the massaging insert and comprises an open connection towards its rear end, such that the negative pressure provided in the base body of the massaging head is connected to the negative pressure cavity, when the massaging insert is connected to the base body.
  • the invention further provides a massage device, comprising a main body having a gripping section, adapted to be held by a user; a massaging head, and an actuator, configured to effect a reciprocating movement of the massaging head relative to the gripping section, wherein the actuator comprises a crank drive, having a drive shaft, which is eccentrically fixed in a crank body, wherein the crank body provides a bearing for a piston rod, wherein the diameter of the bearing is bigger than twice the radius of the eccentricity of the fixation of the drive shaft in the crank body.
  • the invention further provides a method of operation of a massaging device comprising, moving the massaging head reciprocatingly relative to a gripping section and providing a negative pressure within a cavity in the massaging head.
